What we love: Seiko dive watches have earned legendary status, captivating enthusiasts worldwide. From inspiring dedicated Instagram accounts to becoming cult favorites for their appearances on the silver screen, these timepieces hold a special place in the hearts of collectors. While they may not have launched a thousand ships, they come impressively close. This global admiration for Seiko's water-resistant marvels is well-deserved, making every new release worth your attention. Enter the Seiko SPB181J – a perfect addition to this iconic lineage.

The Seiko SPB181J pays homage to its heritage with a case design reminiscent of the Seiko SPB185 and SPB187, both introduced in 2020. These models, in turn, draw inspiration from the iconic 1968 Seiko Automatic Diver ref. 6159-7001. Featuring sloping case sides that seamlessly transition into short lugs, the watch pairs beautifully with its three-link bracelet for a cohesive, robust design. At 45mm in diameter and 12.9mm thick, it’s a bold piece, yet surprisingly wearable due to its compact lugs and the ergonomic fit of the bracelet. Inside, the reliable Seiko caliber 6R35 powers the watch, delivering an impressive 70-hour power reserve and a reputation for durability.
